Routine Description:
Bus drivers must handle BusQueryDeviceID requests for their
child devices (child PDOs). Bus drivers can handle requests
BusQueryHardwareIDs, BusQueryCompatibleIDs, and BusQueryInstanceID
for their child devices.
When returning more than one ID for hardware IDs or compatible IDs,
a driver should list the IDs in the order of most specific to most
general to facilitate choosing the best driver match for the device.
Bus drivers should be prepared to handle this IRP for a child device
immediately after the device is enumerated.
Arguments:
DeviceData - Pointer to the PDO's device extension.
Irp - Pointer to the irp.
